CONVEYING MECHANISM.

Application fi1ed March a, 1924. Serial No. 696,444

My invention relates to conveyers of the type disclosed in my co-pending application, Serial Number 636267, and relates particularly to means for rolling bottlestransversely of a longitudinally moving conveyer.

With large glass bottles and similar ware, it has been found that very strong blasts of air are sometimes needed to roll a bottle transversely of the conveyer, such blasts of air on some occasions tending to deform'the contour of the bottles. The disclosures herein provide means for co-operating with the air blast nozzles in effecting a transverse rolling of the bottles while avoiding any :7 possible deleterious effects as stated.

Another object of my invention is to provide a simple device for the purposes stated.

These and other objects are attained by the means described herein, and disclosed in the accompanying drawings, in which:

Fig. 1 is a plan view of a conveyer comprising means embodying my invention.

Fig. 2 is a fragmental side elevation of the deviceshown in Fig. 1.

Fig. 3 is an enlarged sectional view on line 3-3 of Fig. 1.

Fig. 1 is aperspective view of a track or rail forming a detail of my invention.

The conveyer 10 comprises a frame longitudinally of which an endless belt 11 moves. The belt extends about drums 12 and 13 disposed at opposite. ends of the frame. Motion may be' imparted to the drums in any suitable manner, for example by a chain or link structure 14 driven from a motor 15, supported by the frame. The belt 11 comprises rollers 16 that are connected by suitable chain links 17. The rollers and links carry brackets 18 that support transversely extending bars 19 supporting the belt 11. The rollers 16 ride upon tracks 20 as such rollers pass between the drums. The tracks 20 supporting the up er section of the belt are given generally un ulating upper surfaces 21, the undulations being so related that the high portion or high surface of the track 20 at the left of the frame is disposed opposite to a low portion of the track 20 disposed at the right of the frame, see Fig. 3. This structure has the effect of warping the belt as it moves longitudinally of the frame, thereby imparting a gentle transverse rolling motion to the ware as it is carried longitudinally of the frame.

' Air discharged from the nozzles 22 disposed at the sides of the frame co-operates with the cooling air from chambers 26 formed within the casings 27 extending longitudinally of the frame, and supplied with cooling air from any suitable source, for example as shown in my several co-pending applications, one of which is now Patent 1,487 ,000,

March 18, 1924:. Ware is directed to the belt 11, by any suitable means, such as the chute 28. The chute 28 is adapted to receive the ware from a bottle machine, not shown.

The operation of the device is readily evident from the description as given.

The chain or link structure may be of the type disclosed in my co-pending application Serial 565,732, filed June 3, 1922, wherein an axle extends thru the roller and carries the bracket 18, and links connect adjacent axles. The discharge of air from the nozzles is con.- trolled by valves 40. The air blasts are generally arranged so that succeeding blasts move in opposite directions across the belt.

It is preferable to have the nozzles disposed so that the air discharged therefrom co operates with the undulating motion of the belt in rolling the ware. This makes it unnecessary to use strong blasts and a slight warping of the belt is sufficient to accomplish the object sought. The nozzles and Warping of the belt co-operate most efliciently by having the nozzles direct the blast of air from the elevated portions of the belt toward the lower portions of the belt. The undulations in the opposed rails or tracks are preferably of equal number so that the lengths of the belt at both edges thereof remain constant.

What I claim is:

1. In a device of the class described the combination with a frame of a pair of tracks carried by the frame, the tracks having undulating upper surfaces, the undulations bearing a relation such that the raised portion of one track is disposed oppositely to the low portion of the other track, a belt supported at its edges upon the tracks, and air nozzles for directing blasts of air transversely of the belt.

2. In a device of the class described the combination With a frame of a pair or tracks carried by the frame, the tracks having undulating upper surfaces, the undulations bearing a relation such that the raised portion of one track is disposed oppositely to r the low portion of the other track, a belt supported at its edges upon the tracks, and air nozzles for directing blasts of air transversely of the belt, the nozzles directing blasts of air alternately in opposite directions over thebelt. i

3. In a device of the class described the combination With a frame of a pair of tracks carried by the frame, the tracks having undulating upper surfaces, the undulations bearing, a relation such that the raised portion of one track is disposed oppositely to the low portion of the other track, a belt supported at its edges upon the tracks, and air nozzles for directing blasts of airtransversely of the belt, the nozzles directing blasts of air alternately in opposite directions over the belt, the nozzles being disposed adjacent the high portions of the tracks for cooperating with the undulations imparted to the belt by the tracks, for rolling ware transversely of the belt.v

4. The combination of a conveyer having an unobstructed carrying surface for re ceiving articles adapted for rolling on the said carrying surface, transversely of the line of movement of the conveyer, and undulating tracks for the conveyer for alter ruary, 192 1.
